Description
Technical Field
The invention relates to a construction process of a single pier capping beam of a high pier of a bridge, which can quickly and safely organize construction, in particular to a cast-in-situ bracket system of the single pier capping beam with a higher pier column and a larger cross section.
Background
Along with the development and construction of the country in recent years, more and more mountain expressways are developed and constructed, more and more mountain bridges are constructed, more and more rectangular high piers are in a bridge pier column form, and the high-pier single-pier capping beam has great construction difficulty due to the characteristics of high height, large load, long construction period, high safety risk and the like.
The traditional high-pier single-pier capping beam bracket system is mainly a high-altitude welding bracket method and a steel bar penetrating method. The welding bracket method has the problems that the components need to be welded at high altitude, the welding quality hidden danger and the high-altitude operation risk exist, and the components need to be cut and removed at the later stage, so that the removing difficulty is high, the appearance of the pier body is not attractive, and the like; the steel bar penetrating method needs to install and remove a jack of a frame body on a steel bar, so that the safety risk is high and the frame body is not easy to remove.
The triangular bracket system is integrally connected through the pin, so that the overhead working capacity is reduced, the welding human factors are reduced, all materials are processed in a factory and assembled on site, the safety and reliability are high, the cost is low, the disassembly is convenient, and the later repair and decoration engineering quantity is reduced. Is superior to the traditional construction process in various aspects of safety, quality, construction period, cost and the like.
Disclosure of Invention
The triangular bracket system and the construction method solve the defects of the prior art, are safe in frame body, convenient to install and disassemble and small in influence on a pier body, and are suitable for all bridge rectangular high-pier single-pier capping beam constructions.
In order to solve the above technical problem, the present invention provides the following two embodiments:
a construction method of a rectangular high pier or single pier bent cap of a bridge comprises the steps of embedding bracket boxes symmetrically on a pier body by taking the center of the high pier or the single pier as a symmetry axis before the pier body of the rectangular high pier or the single pier is capped, reserving at least one pair of pull holes on the bracket boxes and the pier body of the high pier or the single pier, after the pier body is capped, inserting brackets with set sizes into the embedded bracket boxes of the pier body, fixing the brackets by opposite pulling through deformed steel bars, placing sand boxes on the triangular brackets, arranging I-shaped steel cross beams on the sand boxes, arranging double-spliced Bailey beams on the I-shaped steel cross beams, arranging I-shaped steel distribution beams on the double-spliced Bailey beams, placing triangular support frames for adjusting bottom molds of the bent cap on the I-shaped steel distribution beams, laying bent cap templates on the triangular support frames, binding bent cap reinforcing steel bars, and finally pouring the bent cap.
In the embodiment, the bracket box is made of a steel plate with the thickness of 3cm,
in this embodiment, when the bracket box is pre-buried, the steel bar mesh is laid under the bracket box in the pier body of the high pier or the single pier.
In this embodiment, the tripod inserts in the bracket, and is fixed through rod iron and bracket pin joint, the tripod is equipped with the trompil in the position that the rod iron passed, and is right the trompil carries out the reinforcement.
In this embodiment, when the bracket system is removed, the sand box is lowered, the triangular bracket is lifted, the screw-thread steel screw nut is unscrewed, and the bracket is pulled out in sequence, and then the local decoration is performed on the bracket box part of the pier body.
The utility model provides a rectangular high mound of bridge or only mound bent cap triangle bracket system, includes pre-buried bracket box in the pier shaft of rectangular high mound of bridge or only mound, the bracket box uses high mound or only mound center to lay as symmetry axis symmetry, reserve at least a pair of drawing hole on the pier shaft of bracket box and high mound or only mound, the cartridge has the bracket in the bracket box, and the bracket is fixed to drawing through the screw-thread steel that passes to drawing the hole, be fixed with the triangle bracket on the bracket.
In this embodiment, the bracket box is embedded in a 300mm pier body of the high pier or the single pier.
In the embodiment, the bracket is made of a steel plate with the thickness of 3mm through double-sided full-welding.
In the embodiment, the triangular bracket is fixed with the bracket through a 40Cr steel bar with the diameter of 7cm in a pin joint mode.
Due to the adoption of the method and the structure, the invention has the following advantages:
1. the whole no high altitude welding of triangular bracket system, all adopt the pin joint, easy dismounting is safe, construction cycle is short, load on the triangular bracket system is from top to bottom finally on whole transmission to the triangular bracket, triangular bracket upper portion is drawn, the lower part pressurized, the horizontal force that the bracket system bore is eliminated to drawing to the finish rolling screw-thread steel that adopts in the pre-buried pier shaft, the pull shear stress that the bracket system bore is eliminated to the rod iron that adopts bracket and triangular bracket between, bracket lower part bracket is pressurized, its bracket box is with lower pier shaft adoption increase the reinforcing bar net piece form and carry out the reinforcement.
2. When the bracket boxes are embedded in the pier body, all the bracket boxes are embedded in the pier body, and after the bent cap construction is finished, the decoration treatment is simple and easy, and the influence on the pier body is small.
3. All components can be used in a turnover mode.
In summary, the present invention adopts the pin joint in the whole course, the load on the bracket system is finally and completely transferred to the triangular bracket from top to bottom, the upper part of the triangular bracket is pulled, and the lower part is pressed. The horizontal force borne by the bracket system is eliminated by adopting the counter-pulling of the finish rolling deformed steel bar in the embedded pier body, the tensile and shearing stress borne by the bracket system is eliminated by adopting the steel bar between the bracket and the triangular bracket, the bracket at the lower part of the bracket is stressed, and the pier body below the steel plate box is reinforced in a mode of adding a reinforcing mesh. All joints of the stressed member are reinforced when being manufactured in a factory, high-altitude welding construction is avoided, safety and reliability of a support system are guaranteed, and unreliable factors of people in high-altitude welding are technically avoided.
